Definitions
- the present invention relates to the general field of recycling lithium batteries and more particularly to recycling Li-ion type batteries.
- the invention relates to a recycling process for selectively extracting cobalt and / or manganese from a solution additionally containing lithium ions.
- the invention is particularly advantageous since the extraction efficiency of these elements is very high.
- the lithium accumulators (or batteries) market in particular of the Li-ion type, is currently growing strongly, particularly with nomadic applications (“smartphone”, portable power tools, etc.) and with the emergence and development of electric and hybrid vehicles.
- Lithium-ion accumulators include an anode, a cathode, a separator, an electrolyte and a casing which can be a polymer bag, or a metal packaging.
- the negative electrode is generally made of graphite mixed with a PVDF-type binder deposited on a sheet of copper.
- the positive electrode is a lithium ion insertion material (for example, UC0O 2 , LiMn0 2 , LÎ 3 NiMnCo0 6 , LiFeP0 4 ) mixed with a binder of the polyvinylidene fluoride type deposited on an aluminum foil.
- the electrolyte consists of lithium salts (UPF 6 , L1BF 4 , L1CIO 4 ) dissolved in an organic base consisting of mixtures of binary or ternary solvents based on carbonates.
- the operation is as follows: during charging, the lithium de-intercalates from the active material of the positive electrode and is inserted into the active material of the negative electrode. When discharging, the process is reversed. Given the environmental, economic and strategic issues in the supply of certain metals present in batteries, it is necessary to recycle 50% of the materials contained in Li-ion batteries and accumulators (directive 2006/66 / EC). In particular, it involves upgrading copper, cobalt, nickel and lithium.
- Physical methods include, for example, dismantling, crushing and sifting batteries.
- the thermal methods are based on pyrometallurgical processes consisting in heating the residues at high temperature to separate the metals in the form of slag or alloys.
- these thermal methods are energy intensive because they require temperatures that can reach 1400 ° C.
- Chemical methods are used to recover valuable items in a pure form. These are hydrometallurgical processes using reagents in liquid phase to dissolve and / or precipitate metals. Traditional leaching uses highly concentrated acids. Separation is achievable by various methods and chemical reagents.
- cells and batteries are subjected to a hydrometallurgical treatment process.
- the process comprises the following stages: dry grinding, at room temperature, under an inert atmosphere, then treatment by magnetic separation and density table, and aqueous hydrolysis, with a view to recovering the lithium, for example in the form of carbonate.
- the fine fraction freed from soluble lithium and comprising the valuable elements is dissolved in 2N sulfuric medium at a temperature of 80 ° C. in the presence of steel shot.
- the cobalt is recovered by precipitation by adding sodium hypochlorite, with pH regulation to a value between 2.3 and 2.8.
- This method is used for a solution rich in cobalt (> 98%) and very low in manganese ( ⁇ 2%).
- electrolysis is carried out at a temperature of 55 ° C. under a current density of between 400 and 600 A / m 2 .
- hypochlorite is harmful for the installations, the safety and therefore the cost of the process.
- manganese concentration it is necessary to know the manganese concentration in order to choose the appropriate process.
- the elution of the nickel and cobalt ions is, for example, carried out with a solution complexing the nickel and / or cobalt ions, for example with aminopolycarboxylic acid.
- the elution of the manganese ions is, for example, carried out with a mineral acid at a concentration of 2N to 4N.
- ion exchange resins are relatively expensive, and need to be regenerated. Their use generates a lot of effluents, long treatment times and a high consumption of acid.
